Hindorff et al. [22]Nonfatal MI/nonfatal strokeABCB1, CETP, HMGCR, LDLR, LIPC, NOS3865 with MI, 368 with stroke and 2686 controls/statinsNo gene-statin interactions for stroke.
5 SNP-statin interactions on stroke (one CETP, four LIPC); no gene level association for stroke; SNP level association: two SNPs (one CETP, one LDLR) for stroke.
The highest significance was found for stroke in CETP rs5883 carriers on simvastatin (OR 3.60 95% CI 1.22–7.70)

Heart protection study [23]Major coronary event (coronary death or nonfatal MI), major vascular event (major coronary event plus revascularization or stroke)KIF6 Trp719Arg polymorphism (rs20455) on vascular risk and response to statin therapy in from of the heart protection study18,348 participants/simvastatinNo significant gene-statin interaction with any of the outcome, including stroke

Rotterdam study [24]Death, MI, strokeApo E (E2, E3, E4)7983 older than 55 yo/statinsNo significant gene-statin interaction with any of the outcome.
Statins reduce stroke risk (aOR 0.50 95% CI 0.28–0.91) independently of Apo E genotype
